The novel is pretty fleshed out, but has the weakness of utter stupidity as plot origin in order for the Mc to come in and trying to rectify the consequences that.
The motivation of most Chars and Mc have depths and politics is also not skimped over.
Story is surrounding the life of a forced fugitive at first and later the protection of what MC build up.
Author is pretty thorough on awareness of minor actors that have an Influence.
Incidentally not understanding the customs and because of "miscommunication" and "charming skills" affecting the community the Mc is visiting, makes it apparently valid for certain characters to just go and join the Harem for the own feels. Not that the Mc cares, he is just happy to have a family and is thankful for all the peeps around him.
The author is pretty creative with surprise elements and in rare cases they can be anticipated.
